Problems solved by technology

[0004] 1) A few centimeters thick concrete protective layer must be poured before the main concrete is poured, which may cause invisible damage to the waterproof layer during the construction of the protective layer;

[0005] 2) During the construction of the main body of concrete, lifting and tying of steel bars, crossing of working surfaces and other activities may cause damage to the completed waterproof layer;

[0006] 3) The number of pre-paved waterproof coiled materials is huge, and the overlap of the coiled materials is prone to operational deviations, leaving hidden dangers of leakage, which in turn causes leakage;

Therefore, on the one hand, the steps of applying and scraping the base t...

Abstract

The invention discloses a composite waterproof coiled material, from top to bottom, in turn including isolating layer, sizing material layer A, enhanced layer, sizing material layer B and close binder. The close binder can be bond closely with the structural layer of a building and set with particle layer. The invention discloses the constructing methods of pre-laying method and wet-laying method of this coiled material, where the pre-laying method can eliminate the procedure of laying protective layer in traditional construction and the wet-laying method can eliminate the procedure of making primary level making layer and has a few requirements for base level and can make waterproof construction. With respect to the existing techniques, it has the characters of simple structure, good waterproofing effect, strong anti-piercing ability, convenient use and maintenance, simple constructing method, etc.

Example Embodiment

[0062] Example 1:

[0063] A construction method of a roof waterproof layer using the composite waterproof coiled material provided by the present invention adopts a wet paving method, and the specific construction steps are:

[0064] 1) Laying the base layer, the steps of laying the base layer include: a. Concrete roof cushion; b. Construction preparation; c. Base layer inspection and acceptance;

[0065] 2) Wet paving pretreatment on the surface of the base layer, that is, applying cement mortar or pouring concrete, and leveling;

[0066] 3) Wet-lay the composite waterproof membrane, the step of laying the composite waterproof membrane is to wet-lay the large-surface membrane, and lay the edge and roll it evenly;

[0067] 4) After the wet-laid cement mortar or concrete is initially set, uncover the release paper on the edge of the composite waterproofing membrane to expose the self-adhesive layer;

[0068] 5) Paste the pre-prepared lap tape on the interface of the two coils, and seal the joints of the flat coils.

[0069] 6) Set a protective layer or paste colored sand to set a colored pattern.

[0070] The main points of construction are:

[0071] 1) Basic level requirements: the basic level must be firm and moist, and the corners of the yin and yang should be made of arc;

[0072] 2) Pressing cement mortar or pouring concrete, using a shallow tooth scraper to press the cement mortar on the surface of the treated base layer, the thickness is 15-20mm;

[0073] 3) Wet-laid large-surface coiled material, wet-laid on the already smeared cement mortar or concrete surface layer, and make the bonding layer of the coiled material closely adhere to the already smeared cement mortar layer or concrete layer, while laying While tapping the coil with a flat plate, pull the coil toward both ends to exhaust the air under the coil;

[0074] 4) Sealing of the indirect seam between adjacent coils: After the cement mortar or concrete is initially set (it is feasible and does not damage the waterproof layer), remove the isolation paper on the edge of the composite waterproof coil, and paste the self-adhesive sealing tape;

[0075] 5)Fixed and closed coil winding head: In the vertical position, the self-adhesive layer of the coil material faces the base layer, and it is bonded with the flat self-adhesive layer and the vertical base layer. The metal bead is nailed and fixed and sealed with special sealing paste and double-sided self-adhesive sealing tape.

[0076] Example 2:

[0077] A construction method of the basement floor waterproof layer using the composite waterproof coiled material provided by the present invention adopts the pre-laying method, and the specific construction steps are:

[0078] 1) Laying the base layer, the steps of laying the base layer include: a. concrete cushion; b. construction preparation; c. base layer inspection and acceptance;

[0079] 2) Pre-laying treatment on the surface of the base layer, you can apply the base layer treatment agent first, and then paste the additional layer on the nodes and special parts, or you can paste the additional layer directly without applying the base layer treatment agent;

[0080] 3) Pre-lay the composite waterproof coiled material, the step of laying the composite waterproof coiled material is to first locate and stretch the line, then glue and lay the large-surface coiled material, and lay the side and roll to make it level;

[0081] 4) Laying the structural waterproof layer is to pour concrete after tying the steel bars.

[0082] The main points of construction are:

[0083] 1) Requirements for the base layer: The base layer must be firm, flat, clean and without water, the corners of the yin and yang should be made into arcs, and the base must be dry at the place where it needs to be stuck;

[0084] 2) Brush the base treatment agent: evenly apply the special base treatment agent on the surface of the base layer, and let it cool until it is not sticky to the touch, or it is not necessary to brush the base treatment agent.

[0085] 3) Additional layer: Nodes and special parts are enhanced according to design requirements.

[0086] 4) Positioning and elastic reference line: In order to ensure the accuracy of the laying position and the straightness of the long side, the elastic reference line should be adhered to;

[0087] 5) Glue the large-surface coiled material, slowly tear the release paper from the back of the coiled material, and at the same time, slowly spread the coiled material forward along the reference line. Exhaust air, so that the coil is firmly attached to the base layer;

[0088] 6) Coil joint lap and seal: uncover the release paper at the self-adhesive lap edge of the coil, and then lap the lap edges of adjacent coils, and coat the exposed black coil with polymer cement Based waterproof coating.
